Urban Explorer Urges Caution at Hazardous Abandoned Maine Mill
10 Nov
Summary
- Keddy Mill in Windham, Maine to be demolished in 2026
- Site designated as Superfund, highly polluted with chemicals
- Floors covered in bird excrement, holes leading to 10-foot drops
In November 2025, an urban explorer has strongly cautioned fellow enthusiasts against visiting the abandoned Keddy Mill in Windham, Maine. The 120-year-old former factory, which operated for paper and steel production before closing in 1997, is scheduled to be demolished next year.
Images of the dilapidated site posted on Reddit show the mill in a severe state of disrepair. Most windows are broken, with walls, floors, and columns covered in graffiti. Inside, rusting machinery, grass, and moss indicate the building has been left to the elements for nearly three decades. The photographer describes the area as a Superfund site, meaning the surrounding environment is highly polluted with hazardous chemicals.
Citing significant safety risks, the urban explorer advises against entering the mill, warning of thick bird excrement coating the floors and dangerous holes that could lead to 10-foot drops. They emphasize the site's unsanitary and unstable conditions, urging people to stay away before the building is demolished in 2026.
